Description

Technical Field

[0001] The present application relates to the technical field of gear production equipment, and in particular to a gear rolling and finishing processing equipment and a processing method. Background Art

[0002] Disc parts are commonly used in engineering practice. Their surface quality directly affects the mechanical properties and service life of the product. For example, the surface quality of gears directly affects their load-bearing capacity and fatigue life. For large and medium-sized disc parts, it is difficult to achieve all-round one-time processing and obtain good surface quality using existing traditional processing technologies such as grinding, honing and lapping.

[0003] However, in the existing grinding processing technology, a three-jaw chuck is usually supported by the inside of the gear to fix the gear, and then a motor fixedly connected to the three-jaw chuck is started, and the motor drives the gear to rotate, so that the grinding device can grind the teeth on the upper surface and side edges of the gear.

[0004] However, when the back of the gear needs to be polished after polishing one side of the gear, the staff needs to remove the gear oil three-jaw chuck, then turn the gear surface over and fix it on the three-jaw chuck. The operation time is long and the operation intensity is high, which affects the work efficiency of the staff. Summary of the invention

[0005] In order to facilitate the turning of the polished gear and reduce the operating intensity of the staff, the present application provides a gear rolling and finishing processing equipment and a processing method.

[0006] A gear rolling and finishing equipment comprises a base, a frame fixedly connected to the base and located above the base, and a three-jaw chuck for internally supporting and clamping the gear, wherein the three-jaw chuck is used to internally support the inner side wall of the gear.

[0007] A grinding mechanism, which is arranged on the frame and reciprocates along the radial direction of the gear during operation;

[0008] A driving mechanism, the driving mechanism comprising a first stepper motor for driving the gear to rotate and a first vertical hydraulic cylinder for driving the first stepper motor to move in a vertical direction, the three-jaw chuck being detachably connected to an output end of the first stepper motor;

[0009] The driving mechanism further comprises a spline rod fixedly inserted into the spline groove, the three-jaw chuck is provided with a spline groove, and the spline rod is fixedly connected to the end of the piston rod of the first vertical hydraulic cylinder;

[0010] A horizontal rotating mechanism, which is arranged on a frame and is used to drive the gear to change direction; the horizontal rotating mechanism includes a rotating cylinder fixedly connected to the frame and a bracket used to be clamped on the gear, the bracket is fixedly connected to the rotating cylinder, the bracket is arranged on the outer peripheral side of the gear, and two sliding wheels are rotatably arranged on the bracket, and the two sliding wheels are symmetrically abutted on both sides of the gear.

[0011] By adopting the above technical solution, when in use, the gear that needs to be ground and chamfered is clamped between the brackets, and the two sliding wheels are symmetrically abutted against the two sides of the gear, and then the first vertical hydraulic cylinder drives the first stepper motor to move in the vertical direction, so that the three-jaw chuck is clamped at the center of the gear, and the three-jaw chuck is adjusted to abut against the circumferential inner wall of the gear, and then the first stepper motor is started to drive the three-jaw chuck to rotate, and the rotating three-jaw chuck drives the gear to rotate, and the grinding mechanism moves horizontally in the radial direction of the gear, thereby contacting the upper edge of the gear teeth during the rotation process, thereby completing the grinding of the upper edge of the gear teeth.

[0012] When the upper edge of the gear teeth is polished, the first vertical hydraulic cylinder starts to drive the first stepper motor to move, so that the spline on the first stepper motor is separated from the spline groove, and then the rotary cylinder is started, and the rotary cylinder drives the bracket to flip, and at the same time, the gear on the bracket also flips synchronously. After the flip is completed, the first vertical moving mechanism starts to drive the first rotary movement to make the spline on the first vertical hydraulic cylinder stuck in the spline groove. In this way, the grinding of the tooth edge on the other side of the gear is continued, so that the gear that is convenient to grind is easy to flip and the operating intensity of the staff is reduced.

[0013] In some embodiments, the horizontal rotation mechanism further includes a limit block, which is slidably disposed along the side wall of the bracket, and the limit block is always used to abut against the lower end of the gear.

[0014] By adopting the above technical solution, the limit block always abuts against the lower end of the gear, thereby achieving the effect of bottoming out the gear and reducing the phenomenon of gear detachment. When the gear is flipped over by the drive of the rotating cylinder, the limit block will slide along the side wall of the bracket under the action of gravity, thereby abutting against the bottom surface under the gear again.

[0015] In some embodiments, the driving mechanism further includes a sleeve, the output end of the first stepper motor is coaxially fixedly connected to the spline rod, the sleeve is sleeved on the output end and one end abuts against the gear, and the other end of the sleeve abuts against the base.

[0016] By adopting the above technical solution, the sleeve is sleeved on the output shaft of the first stepper motor. When the spline is inserted into the spline groove, the end of the three-jaw chuck facing the first stepper motor abuts against the sleeve, thereby improving the strength of the spline and ensuring the stability of the three-jaw chuck during rotation.

[0017] In some embodiments, the grinding mechanism includes a horizontal hydraulic cylinder, a slide rail and a grinding knife. The slide rail is fixedly connected to one end of the frame away from the base. A second stepper motor is slidably installed on the slide rail. The output end of the second stepper motor faces the base. The grinding knife is fixedly connected to the output end of the second stepper motor. The horizontal hydraulic cylinder is fixedly connected to the frame. The output end of the horizontal hydraulic cylinder is connected to the second stepper motor for driving it to reciprocate along the slide rail.

[0018] By adopting the above technical solution, when the gear rotates driven by the rotating cylinder, the horizontal hydraulic cylinder is started at the same time to push the second stepper motor to slide along the slide rail for reciprocating motion, that is, to move along the radial direction of the gear, and in this process, the second stepper motor drives the grinding knife to rotate to grind the upper tooth edge of the gear, and the moving distance of the grinding knife pushed by the horizontal hydraulic cylinder is exactly the depth of the tooth groove, that is, every time the gear rotates through one tooth, the grinding knife just completes extending from the tooth.

[0019] In some embodiments, the grinding mechanism also includes a second vertical hydraulic cylinder and a sliding seat, the sliding seat is slidably set on the slide rail, the second vertical hydraulic cylinder is fixedly connected to the sliding seat, the second vertical hydraulic cylinder piston rod is vertically downwardly set and fixedly connected to the second stepper motor, and the horizontal hydraulic cylinder piston rod is fixedly connected to the sliding seat.

[0020] By adopting the above technical solution, when the gear needs to be flipped, the staff can start the second vertical hydraulic cylinder to drive the second stepper motor away from the gear, thereby increasing the flipping space of the gear during the flipping process and preventing the grinding mechanism from hindering the gear flipping process.

[0021] In some embodiments, the grinding mechanism also includes a support plate, which is installed on the piston rod of the horizontal hydraulic cylinder, and one end of the support plate away from the piston rod of the horizontal hydraulic cylinder is close to the base, and one end of the support plate away from the piston rod of the horizontal hydraulic cylinder is fixedly connected with a reamer, and the reamer is arranged below the grinding knife for sliding close to the tooth side of the gear.

[0022] By adopting the above technical solution, when the horizontal hydraulic cylinder pushes the second hydraulic cylinder to drive the grinding knife to chamfer the edge of the gear, the reamer will move synchronously from the bottom of the grinding knife, and the reamer will move along the tooth side wall of the ground gear, so that the reamer will remove the burrs formed on the gear during the grinding process.

[0023] In some embodiments, the support plate is slidably disposed on a slide rail near one end of a horizontal hydraulic cylinder piston rod, a retaining ring is hinged on the support plate, the horizontal hydraulic cylinder piston rod passes through the support plate in a horizontal direction, and the retaining ring is clamped on the horizontal hydraulic cylinder piston rod.

[0024] By adopting the above technical solution, when it is necessary to adjust the distance between the support plate and the sliding seat, the staff releases the clamping ring on the piston rod of the horizontal hydraulic cylinder, and then adjusts the horizontal hydraulic cylinder to drive the sliding seat to move, thereby changing the distance between the support plate and the sliding seat. After the distance adjustment is completed, the clamping ring is clamped on the piston rod of the horizontal hydraulic cylinder to achieve fixation between the support plate and the piston rod of the horizontal hydraulic cylinder.

[0025] In some embodiments, a slide groove is provided on the sliding seat, and the second stepper motor is slidably disposed in the slide groove along a vertical direction.

[0026] By adopting the above technical solution, when adjusting the height of the grinding knife, the second vertical hydraulic cylinder drives the second stepper motor to slide along the slide groove, thereby ensuring the stability of the second stepper motor during movement and the accuracy after resetting.

[0027] In some embodiments, a vibration-damping wheel is installed on the vertical motor, and the vibration-damping wheel is arranged to roll along the extension direction of the slide groove.

[0028] By adopting the above technical solution, when the second stepper motor slides in the slide groove along the vertical direction, the damping wheel on the vertical motor slides along the slide groove, thereby ensuring the stability of the vertical motor during the sliding process.

[0029] In some embodiments, a method for processing a gear rolling and finishing equipment is also provided:

[0030] S1: Place the gear to be polished on the three-jaw chuck;

[0031] S2: Adjust the three-jaw chuck to press against the inner ring of the gear;

[0032] S3: Insert the three-jaw chuck onto the spline rod;

[0033] S4: The adjusting bracket is sleeved from the outside of the gear to the inside so that the two sliding wheels are respectively in contact with the upper and lower surfaces of the gear;

[0034] S5: Start the first stepper motor to drive the gear to rotate, and at the same time adjust the grinding mechanism to grind the gear along the radial direction of the gear by reciprocating along the tooth groove edge;

[0035] S6: After the gear is polished once in S5, the first stepper motor of the first vertical hydraulic cylinder barrel drives the spline rod to disengage from the spline groove;

[0036] S7: Start the rotating cylinder to drive the gear between the two sliding wheels to flip through the bracket;

[0037] S8: Restart the grinding mechanism and the first stepper motor to grind the edge of the gear on the other side of the gear.

[0038] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] 1. This scheme sets a horizontal rotating mechanism. When the upper edge of the gear teeth is polished, the first vertical hydraulic cylinder starts to drive the first stepper motor to move, so that the spline on the first stepper motor is separated from the spline groove. Then the rotary cylinder starts to drive the bracket to flip. At the same time, the gear on the bracket also flips synchronously. After the flip is completed, the first vertical moving mechanism starts to drive the first rotary moving mechanism to make the spline on the first vertical hydraulic cylinder stuck in the spline groove. In this way, the grinding of the tooth edge on the other side of the gear is continued, so that the gear that is convenient to grind is easy to flip and the operating intensity of the staff is reduced.

[0040] 2. This solution realizes that the first vertical mechanism is separated from the gear clamped by the three-jaw chuck by setting the first vertical moving mechanism, thereby facilitating the rotating cylinder to drive the gear to rotate. BRIEF DESCRIPTION OF THE DRAWINGS
